With all respects for Audioguy3107 and his suggestion of the MSB Link Dac 111. The Link Dac 111 will not hold a candle to the sound quality of the (20 Bit non upgradable) Classe Dac 1. If you can get a good deal on the Classe Dac 1 by all means go for it. The Classe is a very musical sounding Dac and will integrate well with your system. As stated by Onhwy the digital cable you choose will play a big part for the sound quality with the Classe Dac 1.
help with DAC w/current system
I've never used an outboard DAC before, but have a chance at a killer deal on a Classe DAC-1 (Stereophile class A, $4000 retail). I currently have a Rega Planet CD player with a nice Classe amp and B&W speakers. Does anyone know what and how much of an effect a DAC like this would have on a system of this caliber? Any ideas would be appreciated.
